To determine the optimal management of patients with penetrating wounds to zone II of the neck, we performed a prospective evaluation of 120 consecutive patients with such injuries, correlating the results of clinical and diagnostic examinations with operative findings. Seven patients presenting with life-threatening hemorrhage from the neck wound were operated on immediately; the remaining 113 patients underwent arteriography, laryngotracheoscopy, esophagoscopy, and esophagography, followed by neck exploration. ⋯ Five patients were identified with clinical and diagnostic findings that were considered normal preoperatively; however, at operation six major injuries were found in these patients. This study indicates that potentially lethal injuries to major vascular and visceral structures in the neck may go undetected if selective exploration criteria are used in the decision to explore penetrating wounds to zone II of the neck.

We examined the impact of a trauma system on the survival of patients with a Trauma Score of 8 or less. We compared the observed survival with that predicted using a method that calculates the probability of survival (Ps) based on age, physiologic score, and anatomic severity of injury. Of 3394 patients triaged to trauma centers in a 12-month period, 283 (8.3%) had a Trauma Score of 8 or less. ⋯ The Ps was 18%; the observed survival was 29%. Of 60 patients with penetrating trauma and complete data, the Ps was 8%; the observed survival was 20%. We attribute the improved survival to the integration of prehospital and hospital care and expeditious surgery.

During a five-year period, 104 patients underwent a pericardial window procedure to diagnose possible cardiac injury. Eighty-eight procedures were performed by a subxiphoid approach, and 16 were transdiaphragmatic in combination with an exploratory laparotomy. There were 51 patients with stab wounds, 45 with gunshot wounds, and eight with blunt trauma. ⋯ Cardiac wounds repaired included the right ventricle (eight), left ventricle (three), right atrium (five), and cardiac vein or pericardial wounds (three). Complications were negligible and consisted of minor wound infections (two) and postpericardiotomy syndromes (two). The pericardial window provides a rapid and safe means of diagnosing cardiac injuries in patients with equivocal signs of heart injury while sparing the patient without a heart wound a major operation.
